A late goal from Eddie Nketiah gave Arsenal three points that took them a step closer to the Premier League title in a thriller with Manchester United.
Arsenal made the stronger start of the two sides with Martin Odegaard having an early effort blocked before Gabriel Martinelli curled over from inside the box.
They continued to dominate for the opening 15 minutes but it was the away side that took the lead when Marcus Rashford received the ball well outside the box, jinked past Thomas Partey and fired past Aaron Ramsdale from range.
Erik ten Hag's side wasn't in front for long though with Nketiah equalising just seven minutes later, powering in a header from close range to finish off an excellent team move.
